Even first contact doctors can be consulted, surely with extraordinary benefits in the final result of patient care, but especially now in the COVID era that requires greater protection for patients and health workers. We also agree with Dr. Javier Crespo's group that scientific societies and the governments of the countries are even more interested in supporting this type of care and generating the legal bases for this purpose.Apart from pulmonary manifestations, there is an increased incidence of pancreatic involvement and acute pancreatitis (AP) reported in COVID-19 patients. In January 2021, a PubMed search using the terms "Acute Pancreatitis, COVID-19" yielded a result including 94 studies. Most of the studies refer to isolated cases or limited series, with the added difficulty that some authors have considered AP as elevated lipase and/or amylase levels without the diagnostic criteria for AP being met, as highlighted by Chivato et al. in relation to the case they report. Pancreatic involvement has been reported in 17 % of COVID-19 patients and AP in 1.8-2.0 % of these patients..Letter to Editor in reference to Chronic Viral Hepatitis C Micro-Elimination Program Using Telemedicine. The Mexican Experience by Perez Hernandez et al.Endoscopic submucosal dissection (ESD) is a technique for the en bloc resection of early neoplastic lesions in the gastrointestinal tract. A step that must be carried out after excision is the pinning down of the specimen on a support plate such as a cork board to avoid artifacts because of tissue contraction (1). After ESD lesion borders usually curl up from contraction, hence this procedure must be carefully performed to prevent damaging the specimen. Recently, Nishizawa T, et al. (2) reported that dropping adrenaline onto the lesion results in edge relaxation, which facilitates fixation (2). However, the use of other drugs-such as Buscapine-that induce gastrointestinal smooth muscle relaxation, potentially with similar effects, has not been described. Below, two ESD specimens from two different institutions are shown. These specimens correspond to gastric lesions. Buscapine is applied on their surface and the edges become relaxed, thus facilitating stretching and thus fixation. In conclusion, the use of Buscapine may help in the processing of excised lesions by facilitating pinning out and reducing damage risk for specimens.Regarding our article "Daño pancreático pancreatitis aguda en pacientes COVID-19", we would like to clarify that the case previously described met the diagnostic criteria for acute pancreatitis, defined in the Atlanta classification and mentioned in several guidelines.A case of a massive gastrointestinal bleeding secondary to a between esophagus and aberrant right subclavian artery (arteria lusoria) is presented, treated first with haemostatic clips and later with a Sengstaken-Blakemore tube and endovascular stent. A brief literary review is done.Organic electronics is the technology enabling truly flexible electronic devices. However, despite continuous improvements in the charge-carrier mobility, devices used for digital circuits based on organic field-effect transistors (OFETs) have still not achieved a commercial breakthrough. A substantial hurdle to the realization of effective digital circuitry is the proper control of the threshold voltage Vth. https://www.selleckchem.com/products/epacadostat-incb024360.html Previous approaches include doping or self-assembled monolayers to provide the threshold voltage control. However, while self-assembled monolayers-modified OFETs often do not show the level of reproducibility which is required in digital circuit engineering, direct doping of the channel material results in a poor on/off ratio leading to unfavorable power dissipation. Furthermore, direct doping of the channel material in organic semiconductors could cause the formation of trap states impeding the charge-carrier transport. Employing the concept of modulation-doped field-effect transistors (MODFETs), which is well established in inorganic electronics, the semiconductor-dopant interaction is significantly reduced, thereby solving the above-described problems. Here, we present the concept of an organic semiconductor MODFET which is composed of an organic-organic heterostructure between a highly doped wide-energy-gap material and an undoped narrow-energy-gap material. The effectiveness of charge transfer across the interface is controlled by the doping concentration and thickness of an undoped buffer layer. A complete picture of the energy landscape of this heterostructure is drawn using impedance spectroscopy and ultraviolet photoelectron spectroscopy. Furthermore, we analyze the effect of the dopant density on the charge-carrier transport properties. The incorporation of these heterostructures into OFETs enables a precise adjustment of the threshold voltage by using the modulation doping concept.We explore the systematic construction of kinetic models from in silico reaction data for the decomposition of nitromethane. Our models are constructed in a computationally affordable manner by using reactions discovered through accelerated molecular dynamics simulations using the ReaxFF reactive force field. The reaction paths are then optimized to determine reaction rate parameters. We introduce a reaction barrier correction scheme that combines accurate thermochemical data from density functional theory with ReaxFF minimal energy paths. We validate our models across different thermodynamic regimes, showing predictions of gas phase CO and NO concentrations and high-pressure induction times that are similar to experimental data. The kinetic models are analyzed to find fundamental decomposition reactions in different thermodynamic regimes.This study examined the interfacial heat condition between a poly(ethylene glycol) (PEG) self-assembled monolayer (SAM) and water using molecular dynamics simulation. It was found that the PEG SAM has higher thermal boundary conductance (TBC) than the traditionally used alkane-based SAM. The TBC conditionally varied with the length of the PEG molecules, where interfacial thermal resistance was a key factor. Our results reveal that the TBC of the PEG SAM/water interface is greatly influenced by its structural properties rather than the matching of vibrational properties between the SAM terminal and water. The structural analysis shows that the water structure around the terminal oxygen atom of the SAM plays a vital role in controlling the TBC. In this study, the concept of free volume has also been exploited, and the result suggests that the reduction of the free volume fraction accommodates a higher TBC. The model was precisely validated against experimental data by calculating the tilt angle and dihedral angle of the PEG SAM, the persistence length of the PEG chain in the water medium, and the sulfur position of the PEG SAM headgroup on the gold surface using quantitative scanning transmission electron microscopy image simulation.
